Constrained deep neural network architecture search for IoT devices accounting for hardware calibration

no code implementations NeurIPS 2019 Florian Scheidegger, Luca Benini, Costas Bekas, A. Cristiano I. Malossi

The narrow-space search of floating-point models improves the accuracy on CIFAR10 of an established IoT model from 70. 64% to 74. 87% within the same memory constraints.

Constrained deep neural network architecture search for IoT devices accounting hardware calibration

no code implementations24 Sep 2019 Florian Scheidegger, Luca Benini, Costas Bekas, Cristiano Malossi

We further improve the accuracy to 82. 07% by including 16-bit half types and we obtain the best accuracy of 83. 45% by extending the search with model optimized IEEE 754 reduced types.

An Information Extraction and Knowledge Graph Platform for Accelerating Biochemical Discoveries

no code implementations19 Jul 2019 Matteo Manica, Christoph Auer, Valery Weber, Federico Zipoli, Michele Dolfi, Peter Staar, Teodoro Laino, Costas Bekas, Akihiro Fujita, Hiroki Toda, Shuichi Hirose, Yasumitsu Orii

Information extraction and data mining in biochemical literature is a daunting task that demands resource-intensive computation and appropriate means to scale knowledge ingestion.

Corpus Conversion Service: A machine learning platform to ingest documents at scale [Poster abstract]

no code implementations15 May 2018 Peter W J Staar, Michele Dolfi, Christoph Auer, Costas Bekas

We present a platform to ingest documents at scale which is powered by Machine Learning techniques and allows the user to train custom models on document collections.

Incremental Training of Deep Convolutional Neural Networks

no code implementations27 Mar 2018 Roxana Istrate, Adelmo Cristiano Innocenza Malossi, Costas Bekas, Dimitrios Nikolopoulos

We propose an incremental training method that partitions the original network into sub-networks, which are then gradually incorporated in the running network during the training process.

BAGAN: Data Augmentation with Balancing GAN

4 code implementations26 Mar 2018 Giovanni Mariani, Florian Scheidegger, Roxana Istrate, Costas Bekas, Cristiano Malossi

The generator in the GAN is initialized with the encoder module of an autoencoder that enables us to learn an accurate class-conditioning in the latent space.

Mixed-Precision In-Memory Computing

no code implementations16 Jan 2017 Manuel Le Gallo, Abu Sebastian, Roland Mathis, Matteo Manica, Heiner Giefers, Tomas Tuma, Costas Bekas, Alessandro Curioni, Evangelos Eleftheriou

As CMOS scaling reaches its technological limits, a radical departure from traditional von Neumann systems, which involve separate processing and memory units, is needed in order to significantly extend the performance of today's computers.
